JEREMIAH BATES, OF SHERBURNE, MINNESOTA.

MACHINE FOR SEPARATING FLAXSEED.

SPECIFICATION forming part of Letters Patent No. 340,542, dated April 2'7, 1886.

Application filed July 14, 1885. Serial No. 171,608. (No model.)

To all whom, it mag concern:

Be it known that I, JEREMIAH Barns, of Sherburne, in the county of Martin and State of Minnesota, have invented a new and Improved Machine for Separating Flaxsecd, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for separating fiaxseed according to the size of the same.

The invention consists in the peculiar construction and arrangement of parts hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal sectional elevation of my improved machine for separating flaxseed. Fig. 2 is a detail plan view of part of the top screen. Fig. 3 is a detail plan view of part of the intermediate screen. Fig. 4 is a cross-sectional elevation of the vibrating box.

A box, A, is hung by bars B in a frame, 0, in such a manner that it can vibrate in the direction of its length, and in the said frame a hopper, D, is held at one end and above one end of the box A, which hopper hasaslot, D, which can be closed by a slide, E. A rod, F, is pivoted to the side of the box, and is connected with a crank, G, on one end of a shaft, H, carrying a pinion, J, engaging with a cogwheel, K, on a shaft, L, having a crank, L. A short distance from thetop edges of the box an inclined screen, M, is secured, which has transverse slots M. At the lower end of the said screen a spout, N, is formed, which projects beyond the end of the box and is contracted toward its free end.'

Below the screen M another screen, 0, is loeated, which has circular apertures, and is parallel with the screen M, and below the screen 0 a board or partition, P, is placed, which is inclined in the inverse direction of the screen M, and at the lower end of the said partition a spout or outlet, Q, is formed. Below the partition I? ascreen, It, is placed, parallel with the same, and at the lower end of the said screen It aspout, T, is formed, which projects from the side of the box. Below the screen It a metal partition, S, is located, the lower end of which is free.

The operation is as follows: The seed to be separated is placed in the hopper D and slides through the slot D in the same upon the screen M. The sticks, straws, and other coarse matte s with the seed cannot pass through the slots of the screen M and slide upon said screen and from the spout N, the seeds dropping through the screen M upon the screen 0, down which they slide. Large seeds of other kinds do not pass through the'screen 0, but slide down the same upon the last screen, R. The seeds that have dropped through the screen 0 slide down the partition F and drop into a suitable receptacle below the spout Q. The seeds that cannot pass through the screen It pass off through the side spout, T, and seeds that have passed through the screen R slide down the metal partition S. The seeds are thus separated into three kinds and delivered at different parts of the machine.

Having thus described my invention,l claim as newand desire to secure by Letters Patent- In a seed-separator, the vibrating box A, provided with theinclined sieve M, extending from end to end of the box, with itslower end projecting beyond the same and forming a spout-,N, the sieve O,i nclined in the same direction as the sieve M,and extending from the front of the box nearly to the rear end thereof, the

partition P, extending from the lower end of the sieve O nearly to the forward end of the box in an inclined direction reverse to that of the said sieve, the sieve R, extending from the rear end of the box to a spout, T, at the side of the same, near its forward end, and inclined in the same direction as the partition P, and thepartition S, extending from the rear end of the box under the sieve R to nearly the lower end of the same, substantially as herein shown and described.

JEREMIAH B ATES.
